' Thisinvention relates to machines for use in the manufacture of shoes and is illustrated herein as embodied in a heel-seat fitting machine, v i

In the manufacture of'shoes to which wood heels are to be attached, the heel-seat portions of the soles Ofthe shoes are prepared for the reception of'the concave attaching surfaces of the heels by trimmingolf' surplus 'stockaround' the periphery of the heel-seat portion of the sole of each shoe and forming a heel'breast receiving abutment at the heel breastline of the sole. This operation iscommonly called heel-seat fitting.

1 The-heel breast receiving abutments formed in the solesof shoes to which Louis heels are to be attached are often provided by making a transverse cut in'the sole of the shoe, inclined forwardly toward the attaching surface of the sole, thus roducing a flap having a thin end and a thic er base and serving as an abutment beneath which the projecting portion of the breast of a Louis heel canbe positioned, as disclosed and claimed in Let ters Patent of the United States No. 1,527,963,

granted February 24, 1925, on an application filed in the names of John L. Preo and Isabelle Henne. -The heel-seat fitting operation, including the forming of such an abutment, has been successfully performed by heel-seat fitting machines of the type disclosed in Letters Patent Ofthe United'Stat'es No. 1,697 ,251, ranted January 1,1929, on an application led in the names "of Free and Henne, and

by improved machines of the same general type disclosed in Letters Patent of the United States No. 1,661,391, granted March 6, 1928, on an application filed in the name of William'G. Stewart. 7 I

It is an object of thepresent invention to adapt machines of the type referred to above to perform the heel-seat fitting operation upon the soles of shoes to which Cuban heels are to be attached, though the invention is not limited to embodiment in machines of that type.

I The breasts of Cuban heels do not project forwardly and overhang in the fashion characteristic of Louis heels and the heel breast receiving abutment used with such heels commonly takes the form of a pair of shoulders, one at each endof the heel breast line, these shoulders having approximatelyvertical surfaces curved or inclined transversely in accordance withthe transverse curvature ofthe heel breast and deviating fromthe vertical, assuming the shoe to be positioned normally, only sufiicientlyto bring them into alinement with the breast surface of the heel; These shoulders commonly extend the full thickness ofthe sole at the edges of the sole and diminish inheight toward the medianportion of -the shoe, the abutment usually taking the form of two separatedpor'tionsbetween which the sole of theshoe'has not been cut.

' The illustrated machine, which comprises a preferred embodiment of the invention, is

equally applicable to the performanceof the heel-seat fitting operation upon shoes to which other kinds of heelshaving straight 1 breasts are to be attached." It may alsolbe used for the performance'of the heel-seat fitting operation upon shoes to which Louis heels are to be attached. Accordingly, in

this specification and the accompanying claims the word abutment, where used broadly and without qualification, is intended todesignate the surface or surfaces. against which the heel bears at its forward extremlty, regardless of the form of the surface'and regardless" of whether the surface is continuous or is formed of two portions separated or spaced apart.

With the above-stated object in view and in accordance with a feature-0f the invention, the illustrated machine is provided with a rotary cutter movable transversely across the sole of a shOe presented to the machine from one edge of the sole to the other. In order to controlthe' movement of the abutment forming cutter in a simple fash ion' and in a mannei which will not-interfere with the other parts of the machine, the illustrated machine is provided with ,a guide extending transversely across the sole of a shoe carried by a suitable support and along which the cutter is moved as it operates upon the sole. The illustrated machine, like the heel seat fitting machines referred toabove, Is also provided with a cutter for trimming the surplus stock from and beveling the peripheral portion of the heel-seat of the sole, this cutter being controlled as it moves peripherally of the heel-seat in the manner disclosed in an a plication for Letters Patent of the United tates, Serial No. 170,881, filed February 25, 1927 in the name of Harrie A. Ballard.

A further feature of the present invention comprises novel means for controlling the path of movement of the abutment forming cutter of the machine in such a manner that it will be moved heightwise of the sole of a shoe as it is moved transversely thereof. This permits the width of the median portion of the sole untouched by the cutter to be varied in accordance with the size of the heel to be attached to the shoe. For that purpose the illustrated machine is provided with a cam arranged to control the movement of the cutter heightwise of the shoe, the illustrator cam being made up of a plurality of relatively movable sections by adjustment of which the heightwise movement of the cutter may be changed, thus adapting the machine to form the heel breast receiving abutment with accuracy on shoes of different widths.

In accordance with another feature of the invention, the machine is also provided wit means illustrated as a cam for controlling the movement of the abutment forming cutter lengthwise of the shoe so that the abutment will be given a transverse inclination corresponding to the transverse curvature of a heel breast. Thus in the illustrated machine the abutment forming cutter, as it enters the sole at one edge thereof, is moving in a path arranged at about degrees to the median line of the shoe and inclined rearwardly toward the median line of the shoe. After the cutter has moved heightwise out of contact with the sole at the median portion thereof, its direction of movement is changed so that it enters the sole of the shoe and approaches the other edge of the sole at an angle of about 7 0 degrees to the median line, the two ends of the path being symmetrical with respect to the median line of the shoe.

In accordance with a further feature of the invention, the machine is provided with means, illustrated as a cam, arranged to control the angular relation of the cutter to its path of movement and formed to cause the angular relation of the cutter to the median line of the sole to be the same in quantity but opposite in direction when the cutter is operating upon the sole at opposite sides of its median line. Thus, in the illustrated machine, the abutment forming cutter is rotated about an axis which diverges rearwardly from the median line upon one side as the cutter approaches the median line from one side of the shoe and upon the other side as the cutter recedes from the median line upon the other side of the shoe.

In order that the heel breast receiving abutment may be properly positioned lengthwise of the shoe, and in accordance with a further feature of the invention, the guide of the illustrated machine along which the cutter utilized to form the heel breast receiving abutment for Cuban heel work travels in its movenent transversely across the sole of the shoe is arranged for adjustment lengthwise of the shoe. The illustrated machine is provided with a heel measuring gage comprising a fixed heel-engaging member and a movable heel-engaging member between which the heel to be attached to the shoe, or a heel like that heel, may be positioned. Suitable connect-ions are provided between the guide for the abutment forming cutter and the movable gage member so that when the latter is brought into measuring engagement with a heel the former willbe located lengthwise of the shoe in such a position that the cutter, as it moves along the guide, will form the heel breast receiving abutment on the shoe at the position appropriate for the reception of the heel measured by the gage. The rear end of the shoe is positioned both longitudinally and transversely byrnovel gage mechanism which constitutes still another feature of the invention.

Another feature of the invention comprises a presserfoot or holddown member adjacent to and arranged to travel in front of the abutment forming cutter as the latter moves transversely across the sole of a shoe, the holddown member being effective to prevent displacement of the sole of the shoe by the cutter and thus being effective also to insure that the cutter cuts and does not tear the sole. As illustrated, this abutment is sprin pressed toward the sole so that it may yield to conform to the transverse curvature of the sole. Still another feature comprises a holddown member arranged to cooperate with the trimming cutter which removes the sur plus material from the peripheral portion of the heel-seat of the sole ofthe shoe. IVhen operating upon shoes the heel-seat portions of the soles of which are not attached, for example Goodyear welt shoes, the sole attaching seam of which does not extend any substantial distance back of the heel breast line, there is a. decided tendency for the heel-seat portion of the sole to be displaced by the trimming cutter. To obviate this the invention provides a holddown member arranged to ride up over the edge of the sole as the trimming cutter is brought into engagement with the sole and to move with the cutter peripherally of the heel-seat portion of the sole.

In the illustrated machine this holddown takes the form of a conical member surroundmg the trimming cutter and spring-pressed toward the sole of the shoe.

In accordance with av further feature of the invention the work support,'which in the illustrated machine ismovable into and'out of operative relation to the heel-seat fitting instruinentalities of the machine, is provided with means by which it may be locked in operative position against forward as well as downward displacement. The general organization of the work support and its op- Bltlt-lllglllEEtilS is of the character disclosed and claimed in the above-mentionedapplication for Letters Patent of the United States filed in the name of Harrie A. Ballard and includes'a cam yieldingly operated as the crease plates are moved into the rand crease of the shoe. In accordance with the feature of the invention now under discussion, pawl and ratchet mechanism is provided automatically to lock the camand the Work support in operative position, means being provided to release the pawl from the ratchet during the first part of the reverse or work releasing movement or" the controller.

The invention is herein illustrated as embodied in a heel-seat fitting machine of the general type disclosed in the above-mentioned Preo and Henne Letters Patent No/ 1,697,251, and

in Letters Patent No. 1,661,391 referred to, but it should be understood" that in various oi" its aspects the invention is not so limited. Obviously, various ot the features of the invention are capable of embodiment in machines of other types.

lVit-h the above and other objects' and features in view the invention will now be described with reference to the accompanying drawings and pointed out in the claims.

granted on an application filed in the name;

of vl illiam C. Stewart. Like that machine it is provided with a frame comprising leg castings 20,22 at the top of which is supported a bed casting 24 recessed at' the front at O for the shoe which is to be operated upon. The shoe to be operated on is carried by a support 28 comprising a last pin 29 mounted for limited transverse movement in the upper end of a hollow post 30 in which is telescoped a post 32 pivoted to the frame of the machine-at 34, a spring housed within as hollow post 30 and hearing at its lower d against the post 32 urging the post 30 int O recessed at the front to. conform to the ecess 26 of the bed casting 24 is secured to ie latter and movably supports a pair of work engaging and supporting crease plates M LP.

42, thin edges of which are formed and arrange-d to enter the rand crease of a shoe mounted upon a'last carried by the last pin 29 when the support 28 is moved rearwardly into operative position, as shown in Fig. 4.

The outer margins of the crease plates 42 are circular as indicated in Fig. 1, the crease plates being arranged for arcuate adjustment in a circular seat formed in the bed plate 40. The rand crease entering edges of the crease plates 42 have an approximately horseshoe-chaped'form, half of the horseshoe bei formed by the edge of each of the crease plates. The point atwhich these two edges meet is substantially in alinement with the back seam of a shoe carried by the work support when the latter is in its operative position and it is about this point that the crease plates are adjustable.

The machine is also provided with a templet comprising a pair of plates 46, 46 (Fig. 2) in which are formed the two halves of a iorshoe-shaped slot 48 serving to guide 0 50 4) upon which is mounted a cutter 52 movable, when the templet members 46, 46 are in operativeposition, a sent the peripheral portion of the heel seat of the sole of a shoe carried by the work support 28 and having its rand crease entered by t. plates 42. As shown in 4, the templet members 46 are, during the opera- Jtl, best shown in Fig. 1, to provide room the last pin 29 upwardly. A bed plate Fig. 15 is a detail view oi a portion of the tion of the machine, positioned Vertically above the crease plates 42 and are adjustable about the same axis ith respect to which the crease plates are adjusted so that the spread of the slot 48 may be readily varied in accordance with the size of the shoe to be operated upon. To facilitate the presentation of a shoe to the machine and its removal therefrom, the templet members 46 are supported by a table 53 consisting of a pair of parallel plates, one above the other, mounted for forward and rearward sliding movement in ways formed at the top of the frame of the machine.

The cutter-sha t 50 is supported in perpendicular relation to the table 53 by means of a sleeve or bushing (Fig. 4) passing through appropriate large openings in the plates of the table 5 3, and provided with a circular plate positioned between the plates of the tab e 53 and having an enlarged hub 56. A collar 57 clamped to the shaft 50 above the sleeve 54 prevents downward displacement of the cutter-s iaft 50.

A ever 58 at the right hand side of the machine (as viewed in Fig. 2) is secured to a rock shaft 59 extending through the frame of the machine and having fast to its inner end an arm 60 4) to which connected :1 rearwardly extending link 61 connected to the table 53 by a pin and slot connection. A spring 62 connected at one end to the link 61 and at the other end to the table 53 causes the table 53 to move forwardly as the upper end of the lever 58 is moved forwardly and provides a yielding connection so that the lever 58 may be moved a short distance after the front of the table 53 comes into engage ment with a stop 63 (see Figs. 2 and (3) arranged to limit its forward movement. The rear end of a dog 64 (Fig. 2) carried by the lever 58 is arranged for engagement with a shoulder 65 secured to the frame of the machine to retain the table 53 in its forward position.

The means for moving the crease plates into and out of engagement with the rand crease of a shoe carried by the work support 28, after the latter has been moved rearvardly from the position shown in Figs. 1 and 2 to the position shown in Fig. 4, and for correspondingly adjusting the templet members 46, is of the character disclosed in said application for Letters Patent of the United States Serial No. 170.881. filed in the name of Harrie A. Ballard. :Lccordin ly, the machine is provided with a hand lever 66 fulcrumed at 67 to the frame of the machine and provided with an upwardly extending portion 68 to the upper end of which is connected a rearwardly extending link 70. The rear end of the link 70 is bifurcated and straddles a transversely extending lever 72 (Figs. 4, 6 and 15) the left-hand end of which is fulcrumed to the frame of the machine at 78. A spring 74 (Fig. 4) is anchored at one end to the top of the link 70 and at the other end to the lever 72. The median portion of the lever 72 is connected by a pair of links 76 with the crease plates 42. Thus, when the forward end of the lever 66 is moved downwardly, the lever 7 2 will be moved forwardly and the crease plates 42 will be moved about their axis in such a manner tiat the spread of the opening between their thin rand crease entering edges will be narrowed and the crease plates will be brought into engagement with a shoe carried by the work support 28 in the position shown in Fig. 4. On the other hand, when the lever 66 is moved upwardly, the spread of the opening between the rand crease entering edges of the crease plates will be widened.

T he machine is also provided with another transversely extending lever 80 6) approximately parallel to the lever 72 and connected at its forward end with the templet members 46 by a pair of links 82. A spring 84 tends to urge the right-hand end of the lever 80 forwardly, thus narrowing the spread of the horseshoe-shaped slot 48. An arm 86 depending from the lever 80 is, however, normally engaged by a corresponding arm 81 (Fig. 15) extending upwardly from the lever 72 in front of the arm 86 so that the lever 80 follows the lever 72 as the latter is swun about its fulcrum and, accordingly, the spread of the horseshoe-s aped slot 4o corresponds to that of the rand crease entering edges of the crease plates 42 when the parts in operative position. For purposes of adjustment in setting up the machine and to compensate for wear the depending arm 86 of the lever 80 is provided with a stop screw 88 (Fig. 6) arranged to contact with the upstanding arm 81 of the lever 72 and thus permitting relative adjustment of the crease plates 42 and the templet members 46.

To move the trimming cutter 52 peripherally of the heel-seat portion of the sole of a shoe to be operated on, a. forwardly extending hand lever 92 is fulcrumed at 90 to the table 53. The hand lever 92 l, 2, 3 and 6) has fulcrumed to its median portion, at 94, a transversely extending hand lever 96 the left-hand half of which is widened, taking the form of a plate 98 (Fig. 6) and bearing upon the top of the table 53. Secured to the plate 98 is a gear housing and guard 100. The sleeve or bushing 54, in which the shaft 50 rotates, extends upwardly through the plate 98, so that the cutter-shaft 50 may be moved peripherally of the heel-seat of the shoe to be operated on by moving the levers 92, 96, one of which is held in each hand of the operator.

The driving means for the cutter 52 includes a vertical shaft 106 (Figs. 4 and 6), the lower end of which is coupled to the shaft 50 (Fig. 4). The shaft 106 rotates in I bearings carried by the housing- 100 and fast upon it is a spiral gear 108' driven by a similar gear upon the forward end of a shaft 110,

the rear end of which telescopes with and is splined to the forward end of another shaft shaft 118 is connected by a universal joint 122 to another vertical shaft 124, which latter'is connected by a universal joint 126 with a third vertical shaft 128 carrying a spiral gear 130 driven from-a larger spiral gear 132 mounted upon a shaft 134 which is connected by suitable coupling 136 (Figs. 2 and 6) to are A therotorshaft138 (Fig. 2) of a motor 140 carried by the lower portion of the frame of the machine. Thus it will be seen that the connections between the motor 140, which is stationary, and'the cutter shaft 50 are such that the latter may be driven at all times regardless of the position of the table 53 and regardless of the traversing movement of the shaft 50 peripherally of the heel-seat of a shoe presented to the machine.

Cooperating with the work support 28 and the crease plates 42 to position the shoe to be operated upon'by the machine is a gage, shown in Figs. 3 and 4, and in detail-in F ig. 13. This gage comprises a back gage memher 152, the work engaging portion of which is inclined forwardly and upwardly (as best shown in Fig. 4) and engages the count-er portion of the shoe substantially at the back seam and just below the flange of the counter. The back gage member 152 may be adjusted forwardly or rearwardly in a groove formed in the bed plate 40 by means of a screw 156 (Fig. 4) provided'with a pair of collars'one forward and the'other to the rear of a hug 158'depending from the back gage 152. The screw-156 is threaded, as shown in i, into a portionv of the bed plate 40. A. centering gage member, 160, the details of which are also shown in Fig; 13, is carried i bythe bed plate 40 adjacent to the back gage ATh'ecentering gage member 160 also has a body portion 162, mounted'for forward and rearward free sliding movement in a groove carried by the bed plate 40, and is provided at its forward end with a pair of arms each provided with an inclined surface 164 arranged to engage the sides of the counter.

portion of a shoe presented to the machine. Thesurfaces 164 are arrangedto converge lengthwise of the shoe positioned in the machine so that if a shoe carried by the work support 28 strikes one of the surfaces 164 before it strikes the other, the shoe will slide relatively to the surfaces 164 with which it is in contact until it contacts with the other gage surface 164,1after which further rearward movement of the work support 28 and the shoe will cause the'gage member 160 to move bodily rearwardly. The surfaces 164 70' are also arranged to converge heightwise of the shoe positioned in the machine so as to assure their engaging the shoe only along portions thereof adjacent to the sole of the shoe. Thus, the centering gage member 160 is operative to center the heel-seat portion of.

the shoe in the machine while the back gage 152 positions the shoe lengthwise in the machine. A light spring 163, the rear end of which is secured to a pin 165 carried by the gage member 160 and the forward end of which issecured to a stationary part, tends to hold the centering gage160 forward.

The work support 28 is moved into and out of operative position with the aidof the hand lever 66 to which it is connected. Rigidly connected with the lever 66 is a downwardly extending arm (Figs. 1 and 4) the lower end of which carries a pin 172 positioned in an approximately horizontalslot 174 formed l'FQll'lZ-llQ rear end of a link 176 the forward end of which is bifurcated and is provided with a pair of short slots 177 (one 1n each of he bifurcations) through which pass pins 178 connecting the link 176 with a pair of duplicate cam members 180. A pair of rolls 182 carried by the hollow post or sleeve 30 of the work support 28 are arranged for operative engagement with the cams when the latter are rotated in a counterclockwise .Ji

direction from the position shown in Fig. 1 to the position shown in Fig. 4. A spring 184 connected at one end to the arm 170 and at the other end to a yoke 186 pivotally connected at 178 to the cam members 180 forms a yielding connection between the arm 170 of the lever 66 and the cams 180 so that the latter will move yieldingly in a rearward direction as the forward end of the lever 66 is depressed. forward end of the lever 66 is raised, the pin 172 strikes the forward end of the slot 174 and the cams 180 are positively rocked in a forward direction. Figs. 2 and 4, pawl and ratchet mechanism 190 is provided to hold the lever 66 in any position to which it may be moved.

When the work support is in inoperative position, as shown, for example, in Fig. 1, the work support 28 is inclined forwardly, the hollow post 30 being elevated by its spring. When the operator places a shoe upon the last pin 29, however, he depresses thevshoe and swings the work support 28 rearwardly at the same time moving the forward end of the lever 66 downwardly and manipulating that lever so that the crease plates 42 are brought into engagement with the inturned'heel-seat. portion of the shoe On the other hand, whenthe It As best illustrated in upper against the lower surfaces of the crease plates 42 is sufficient to maintain the work support 28 depressed until the cam members 180 are moved into engagement with the rolls 182. Further depression of the forward end of the lever 66 causes the cam members 180 to move the work support 28 upwardly, the force required for this being transmitted through the spring 18 i and, accordingly, being, limited to what can be transmitted by that spring. To retain the cam members 180, the work support 28 and the shoe in the position to which they have thus been moved, and to prevent the displacement of the shoe under the forces incident to the trimming operation, pawl and ratchet mechanism is provided for locking or latching the cam members 180 in adjusted position. This, as best shown in Fig. 4, comprises a pair of stationary ratchet segments 190 secured to the frame of the machine, one ratchet segme or the other being engaged by of two groups of pawls 192 pivoted at 19 1 to the cams 1S0. pair of upwardly extending fingers 196 are fulcrumed at 34 to the frame of the machine. The rear surfaces of the upper ends of the fingers 196 are positioned for engagement by the forward end of the link 176 while the forward surfaces of the same portions of the fingers 196 are engaged by a pair of dogs 198 (Fig. 4) pivoted at 19 1 to the cams 180 and having portions 200 positioned to engage the lower surfaces of the pawls 192. Springpressed plunger-s 202 tend to hold the pawls 192 in engagement with the ratchet segments 190.

It will be seen that when the forward end of the lever 66 is depressed and the lower end of the arm 170 is moved to the rear, the fingers 196 will in no way interfere with the depression of the pawls 192, but when the forward end of the lever 66 is moved upwardly, the first edect of the corresponding movement of the link 176 will be to :OClZ the fingers 196 slightly in a clockwise direction, as viewed in Fig. 4, thus rocking the dogs 198 in the same direction and causing them to lift th" pawls 192, thus releasing the ratchet 190 so that the cam members 180 are freed and can rock in a clockwise direction to permit the lowering of the support 28.

At the left-hand side of tle frame of the machine is a carriage 210 (Fig. mounted for forward and rearward adjustment in accordance with the length to which a heelseat is to be trimme l. Mounted for transverse sliding movement in this carriage is a bar 212 at the right-hand end of which is a knife or cutter 21. 1 arranged by transvers. movement of the bar 212 to cut transversely across the sole of a shoe carried by the work support 28, thus forming in the sole a flap having av base of substantial thickness and tapering to a thin end, which flap may serve as an abutment for 0. Louis heel disclosed hove-mentioned Letters Patent of the ttes No. 1,527,963, granted on an ztion filed in the names of Preo and At its left-hand end the bar 212 is ected, as'shown in Figs. 1, 3 and 6, by a A 216 to a bell crank lever 218 fulcrumed at 229 to the frame of the machine and arranged to be rocked by a treadle rod 222 to use the suite 214 to cut transversely across sole and then to be returned to its inoperative position, shown in F ig. 2.

The upper end of the shaft 260 and the forward end of the shaft 268 both have a bearingin a housing 283 which contains the spiral gears 262, 264, this housing being provided with a boss 284 having a bearing in an arm 285 formed as an extension of the collar 236. Thus," the housing 283. can pivot about the shaft 260 relatively to; the cutter carrier 232 as the carriage 226 and the parts carried thereby aremoved along the guide 224.

As the cutter 242 is moved transversely across the sole of a shoe carried by the work support 28 from one edge of the sole to the other at its heel breast line, it is desired that the cutter 242 shall follow a path closely approximating the transverse curvature of the breastof a Cuban heel. It is for this pur pose that the slide 227 is provided. The slide 227 carries a cam roll 292' (Fig. 8) positioned in acam groove 294 formed in the lower surface of the guide224 and of such a configuration that, as the carriage 226 is moved transversely. of the shoe on'the guide 224, the cutter carrier 232 and the cutter 242 wil'lbe movedv longitudinally of the shoe in a path inclined to correspond to the-curvature of the breast of a Cuban heel, that path being symmetrical with respect to the median line of the sole of a shoe carried by the'work supportand positioned by the gage members 152, 160. As illustrated, the path of the cut ter 242 is inclined at about 70 degrees to the median line of the sole. as indicated by the position of the abutments 293 in the sole 295 of the shoe 297 shown in Fig. 16.

In order that the heel breast receiving abutments will extend through the full thickness of the sole at the edges of the sole and will gradually diminish in depth toward the median line of the sole, terminating, however, before the median line is reached, means is provided for moving the cutter heightwise of the shoe as it moves transversely across the sole. For this purpose, the sleeve 229 is arranged for vertical movement with respect to the enlarged portion 228 of the slide 227 and the carriage 226. Fulcrumed at 300 (Fig. 7) to the carriage 226 are a pair of levers 302 having at their rearward extremities a pair of pins 304 to which are pivoted a pair of blocks 306 positioned in slots formed in'the collar 230. One of the levers 302,

the left-hand one as viewed in Fig. 8, is provided with a gear segment .308 (Fig. 7 meshing with a rack bar 310 mounted for forward and rearward sliding movement in the carriage 226. The rack bar 310 carries a roll 312 (Fig. 8) positioned in a cam groove 314 formed in the upper surface of the guide 224 and of such a formation that, as the carriage 226 and the cutter 242 move from the position shown in Fig. 8 toward the left, the cutter 242 enters the sole to its full depth. As the roll 312 reaches the position 316, however, the cutter 242 by that time havand gradually lifting the cutter 242 so that the latter passes out of the sole at the point indicated at 315 in Fig. 16 before'the median line of the sole is reached. After the cutter 242 passes the median line of the sole, the roll 312reaohes the position 318 (Fig. 8) in the cam groove 314 and the cutter 242 is lowered so that it enters the sole at the point indicated at 317 in Fig. 16, finally cutting through the entire thickness of the sole before the edge of the sole is reached. The relation of the cutter 242 to the sole 295 of the shoe, .at the time the cutter enters the sole, is indicated diagrammatically in Fig. 7.

In order to, permit the machine to operate effectively upon shoes of different widths and to permit theitwoseparated portions of the heel breast receiving abutment to be spaced. different distances apart, portions of the surfaces that form the cam groove 314 are formed upon a number of relatively adjustable parts, as best shown in Figs. 8 and 9. Thus, the forward surface of the cam groove 314 is formed upon two portions 320, 322 relatively adjustable by means of a screw 323 having right and left-hand threaded portions threaded into these parts and having a knurled head 324 positioned in a slot 326 formed in the guide bar 224 and preventing longitudinal movement of the screw.

A stationary member 328 secured to the guide bar 224 has a surface also forming a part of the cam groove 314 and overlapping the cam. surfaces formed upon the parts 320, 322, regardless of the adjustment of those parts. A portion of the rear surface of the cam groove 314: is also made up of surfaces formed on overlapping parts of the members 320, 322. Thus, the heightwise movement of the cutter 24-2 can be varied by manual adj ustment of the screw in accordance with the width of the shoe to be operated upon. As shown in Fig. 8, a scale 330 is provided on the guide 22a to facilitate this adjustment.

In order that the cutter 242 shall act lilciently and shall not tear the material of the sole, it is arranged to enter the sole in such a manner that the projection of its axis upon the plane of the tread surface of the sole will be inclined rearwardly from the median line of the sole, the inclination being the same in degree but opposite in dir ction in operating upon 0 )posite sides of the sole. To accomplish this, a cam groove 8) is formed in the lower surface of the g i e 224. In this cam groove is positioned a roll carried by a rod 338 (Figs. 7, 8 and 10) mounted for forward and rearward sliding movcn'ient with respect to the slide 227. Near its rearward end the rod 338 is provided with a series of rack teeth 339 engaging with clongated pinion teeth 3l0 formed on the bearing member Thus, movement of the rack bar 338 relatively to the slide 227 will rotate the cutter carrier 232 about a vertical axis. The formation of the cam groove is such that the cutter 242 enters the sole with the projection of its axis upon the plane of the tread surface of the sole at about nine degrees to the median line of the sole and diverging rearwardly therefrom. After the cutter has been moved heightwise out of engagement with the sole, the cam 33%- moves the rack bar 338 to swing the cutter carrier about eighteen degrees in a counterclockwise direction, as viewed in 8, this being accomplished by the portion of the cam indicated at 3-11 in Fig. 8, so that the project-ion of the axis of the cutter 242 upon the plane of tee tread surface of the sole is brought into a position at nine degrees to the median line of the sole and diverging rearwardly therefrom on the other side of the median line.

A. pair of springs 346 (Fig. 7) secured at one end to the cutter carrier 232 and at the other end to the rearward portion 228 of the slide 22? tends to counterbalance the weight of the cutter carrier 232 and the parts carried thereby and facilitates the lifting thereof.

In order that the angular relation of the cutter shaft 250 to its path of movement may be maintained in the desired relation, notwithstanding the back-lash which is unavoidable, the cutter carrier 232 is provided with an outwardly extending arm 350 (Figs. 7, 10 and 11) provided with a pair of holes 352, 35s (Fig. 11) arranged alternatively to re ceive the rounded upper end of a pin 356 (Fig. 10) extending upwardly from a brackct 358 which depends from the slide When the cutter carrier 232 is in the elevatod position which it occupies while the cutter passes over the median portion of the sole of the shoe, the finger 350 is sulliciently elevated to clear the upper end of the pin 356, but as the cutter carrier 232 is moved downwardly under the control of the cam groove 314, one hole or the other, according to the angular position of the cutter carrier, will receive the pin 356 so that the cutter carrier will be held securely in position while the cutter 21-2 is operating upon the sole.

The cu er 242 should, when in its inoperve position, just clear the top of the crease aim-" s 4-2. To facilitate its vertical adjust-- ment, a slot is formed in the sleeve 229 in which is received the flat head of a screw (Fig. 10) threaded into the collar 230. The upper end of the screw is slotted so that it may be engaged and turned by a screw driver. It will be seen that when the clamp screw which secures the collar 230 to the sleeve 229 is loosened, rotation of the screw 355 will adjust the collar 230 lengthwise of the sleeve thus raising or lowering the cutter carrier When the adjustment has been made. the clamp screw of the collar 230 is again tightened so that the adjustment will be maintained.

To prevent displacement of the sole by the cutter 242, particularly when operating upon shoes the heel-seat portions of the soles of which have not been attached, the machine provided with a holddown member 360 (shown in Fig. 7 but omitted from Fig. 4 to avoid confusion) secured to the cutter carrier and mounted to engage the uncut sole just ahead of the cutter 242 as the latter moves across the sole. The holddown member 360 is mounted for swinging movement heightwise of the shoe about a horizontal pin 362 carried by a bracket 364 secured to the cutter carrier 232 and is pressed yieldingly downwardly by a spring plunger 366 also housed in the bracket 36 Similarly, the rotary cutter 52 which trims surplus stock from the peripheral portion of the heel-seat is provided with a holddown member 370 (see Fig. 4) in the form of a truncated. cone surrounding the cutter 52 and spring-pressed downwardly by a spiral spring 372 surrounding the reduced upper end of the holddown 370, the spring 372 bearing at its lower end against a shoulder formed on the holddown 370 and at its upper end against a collar 374 clamped to an extension 375 of the bushing 54:. A pin 377 passes through the holddown 370 into a slot formed in the extension 375 and prevents excessive downward displacement of the holddown 3'50. As the table 53 is brought forwardly into operative position,the conical surface of the holddown member 370 rides bar 212 and the guide 224 for the cutter 242,

is forwardly and rearwardly adjixstablehfor which purpose itis providedwith a boss 38() (Fig. 1) internally threaded to receive an external thread 382 (Figs 1 and 6) formed on the projecting hub ofa dial member 384; V

The hub 384 is internally threaded to receive a/thread 386 formed upon the stem of a dial 388, the'arrangementbeing ofsthe character disclosed in. Letters Patent" of the United States No. 1,661,391, granted on an application filed in the name of VVilliam C. Stewart. A set-screw 389 isprovided which the dial 384 and screw-382 may beclamped in. posif tion when it is not desired'to use them, as when using a heelmeasuring gage, which will presently be described. H

When using the knife'214-to form. abutments for Louis heels, the carriageJ21O may Y be adjusted bysetting the 'dials'as described in said Letters Patent No'. 1,661,391. vWhen operating upon shoes to which Cuban heels are to be attached, however, a more accurate lengthwise adjustment (if the carriage 210 than can be obtained by the dial mechanism is desirable. Accordin'gly, the carriage 210 is provided with a table 4QOfhavin'gtoward its 'forward end a convex gage niem'ber; 402 of a curvature coriesponding tothat ofthehrea'st of a Cuban heeL Carried. by the frameo'f the machine and "cooperatihg with the gage member 402 is a fixed gage 'memberf404 ar ranged to engage the rear endof a'heelpo's'itioiied upon'the' table 400. Thus, 'a heel 406, either the heel which isto be attached to 'th'e shoe to be operated upon or'a'heel liketliat heel, may be placed upon'the'table 400'afnd moved by'rotating the dial 388, thereby 'nioving thecarriage 210 ui'i'til the heel is'cla'mped li 'htly between the gage 1nen'1bers402, 404 and is measuredthereby. As the'g uid'e f2 24 is'also carried by thecarriage'210,"the position of the cutter 242 forwardly "zihcl'fttr-m wsrdly of the J machine is thus controlled by the length of the heel 406inthe'gage 402, 404. In order to limit the forward movement of the cutter-52 inaccordaiice withtheleng'th of the heel 406 ne'asuredbythe gage loa, 404, or, when Leuisheel wail; i'sjbifi'gdohe, in accordance with the setti ng 'o'f'th'e dials 384, 388, a plate '410 (Figs. 1, 8 aiidj12) is adjustably secured to thejgui'de'bar 224ih such apos'itionthat a willnotfinterfere with I the movement otthe'carriage226 and itsassociated parts. The rear-edge of this-plate 410is long enough to extend across both ends of the horse-shoe-sl1'aped path of movement of th'eh'uba56 when operatingupon an kinds of shoes. Thus, the length of the trimming cut is coordinatedwith the position of the heel breast receiving abutment formed by the machine. i a In order to move the carriage 2 26 trans versely. of the machine to cause the cutter 242. to forma heel breast receiving abutment inltlie sole of a shoe the carriage 226- is cqn nected by a lin k'42'0 (Fig. 2') to a rack bar 422 mounted for horizcntalsliding movement in ways424 carried by the frame of the machine and vprovided with inclined teeth. A 'rhck bar 426 mounted in Ways 428 extendingat rightangles to theways 424 is also provided with inclinedteeth meshing with the teeth of the rack bar 422 in such a mannerthat downwardmoveinent ofthe rackbar 426 will cause} the rack bar 422, the carriage 226*ajn'd the cutter 242 to move tothe left and upward movement of the rack bar 426 will cause those parts to move to'the right. The lower end of the rack bar 426 is connected by a link428 to a hand lever 430 fulcrunied ati432;to"the frameof the machine for vertical swinging movement. H I

The illustrated machine may be used to pger'form'the heel-seat fitting operation upon shoes to which Louis heels are to be attached in the manneri described in the abov e m'entioned Letters Patent .No. 1,661,391, the cutter 214 cutting a flap in the sole beneath which the forwardly projecting portion of "the breast of the heel is positioned. When it to. perform the heel-seat fitting o eiation upon a shoe to which a Cuban heeli's o be at tached, the operator places the heel t'o'be'attahed-to the shoe, or a heel 1iketh'at1iee1,i0n the table 400, turning the dial 388 until the heel is clamped lightly between the gage members 402, 404.. Thissets the carriage 210, guide bar 2-24- an'dthegplate 410 in the appropriate positions forthe shoetobe'operated upon. He then places the last upen which thexshoe'is carried .on thelast'pin 2j9, depressthe'work support 28' and moving itrear- Wardly so thatr'the rand crease otthejshoe may be engaged by 'the'ed'ges of 'the crease plates He then depress'es the lever "66, movingthe 'edges'of th'e creaseplates 42in'to the rand creaseand causingcounterclockwise movement of the cams 180 (as viewedin'Fi'g. 4),...thus causing the spring 184 to urgethe' workfsupp ort yieldingly upwardly,'andfinal- 1y "causing one ofthe'p'a wls 192 to lock the -worksupport in position so tliatit'can uot'be I the heei-seatpbrtinn of the-soleiotthe shbe position indicated at 436 in dotted lines. '1 he lever 58 is then moved rearwardly, Withdrawing the table 53 and the cutter 52, and the lever 4:30 is moved downwardly, causing the carriage 226 to move to the left so that the cutter 242 enters the sole of the shoe at the right-hand side of the machine and moves transversely across the sole from one edge to the other in a path the operative portions of which are substantially straight but correspond closely in inclination to the transverse curvature of the breast of a Cuban heel. During this movement, as already set forth, the cutter 2&2 is moved heightwise of the shoe so that the heel-seat receiving abutment formed is in tWo' parts separated by the uncut median portion of the sole. While the cutter is passing idly over this uncut median portion of the sole, its axis is swung from an angle of about nine degrees on one side of the median line of the sole to an angle of the same size on the other side of the median line, so that the cutter both enters and leaves the sole with its axis at an advantageous angle to its path of movement.
